Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a basic input/output system (BIOS) and a processor. In some examples, the processor is to receive an enrollment message for a function of the electronic device from a server, and send the enrollment message to the BIOS. In some examples, the BIOS is to store the enrollment message in a BIOS memory. In some examples, the BIOS is to verify the enrollment message in response to a function activation request from the processor. In some examples, the processor is to enable the function based on a function activation response from the BIOS.

Abstract: Examples herein disclose receiving a basic input output system (BIOS) policy change and authorizing the BIOS policy change. Upon the authorization of the BIOS policy change, a first copy of the BIOS policy is stored in a first memory accessible by a central processing unit. Additionally, a second copy of the BIOS policy change is transmitted for storage in a second memory electrically isolated from the central processing unit.

Abstract: An example non-transitory machine-readable medium includes instructions that, when executed by a processor, cause the processor to analyze a video captured by a computing device to detect a sequence of motion in the video, and select an audio endpoint of the computing device based on the sequence of motion.

Abstract: In a state of a system in which a processor of the system is not accessing a first memory, a controller in the system determines whether system boot code from the first memory in the system is compromised, wherein the first memory is accessible by the processor and the controller over a bus. In response to determining that the system boot code is compromised, the controller retrieves system boot code from a second memory in the computing device to replace the system boot code in the first memory, where the second memory is electrically isolated from the bus and is inaccessible by the processor.
